Abstract

VERIFICAçãO DE VALIDADE DE CERTIFICADO. Trata-se de um método para verificar uma validade de um certificado (600) contendo uma chave associada a um dispositivo de rede (601) em uma rede, o método compreende receber na rede um conteúdo criptografado (611) e um índice de validade (620) associado ao conteúdo. A validade do certificado é avaliada a partir de um índice de tempo (606) contido dentro do certificado, sendo que o índice de tempo tem um valor correspondente a um momento de emissão do certificado e do índice de validade associado ao conteúdo criptografado.
